+Summary: [PATCH] Signal handlers problem on os x.
 When a null exception is thrown in mono on os x, it will invoke the crashreporter. 
 This is a known bug in os x, where the crashreporter is invoked although there is a null 
 exception signal handler. I filed a bug on this with Apple but they refuse to fix the issue.

+The attached patch fixes the "problem" by installing a dummy
+mach exception handler.
+The logging in ~/Library/Logs/CrashReporter/ will be disabled
+together with the annoying 1-2 seconds delay.
+I didn't test it on x86, just on PPC.
+Test case: :-)
+class T
+        static void Main ()
+        {
+                try {
+                        null.Equals (null);
+                } catch {
+                        System.Console.WriteLine ("ok");
+                }
+        }
